More than 143 million Americans live in an earthquake zone and face at least some risk of a damaging earthquake by 2065, according to a U.S. Geological Survey analysis.
Notes on verification
Confirmed by official USGS press release and multiple independent news sources (CNN, CBS, Weather Channel) citing the same 2015 USGS/Earthquake Spectra study led by Jaiswal, Petersen, and Leith. The 143 million figure and 50-year risk window are consistently corroborated. [tier=gold indep_score=0.963 clusters=4 claim_tier=notable]
